Hi. with regard to RS Vol2>Lab4>Task 4.3 that relates to AS-override feature, the breakdown said this feature replaces the "previosly last" AS# with local AS; but for example, R6 sees the prefixes originated inside AS 54 as this. (150.1.44.44 points to T4):
* 28.119.17.0/24 150.1.44.44 0 400 54 i
it means this prefix is originated at AS 54 and after passing through AS 400, enters to AS 100 (that is R6, which the above command has issued on it). so if we issue the "as-override" command against BB1, the term "last previosly" mentions to what AS exactly? I think this term points to AS 400, but it must be incorrect!! so which AS number is effected or replaced by AS-override feature? tnx.
